The 32.5 *NutsffS-Tifai'elthread-edf on 'the'posts" 3G stops 11 are located on one side of the shaft and engage the upper and lower surfaces 110 5, as shown in Figure 3. A latch 12 is of the crosshead 32. The nuts 37 co11- mounted for recprooationon the platform stitute means whereby the ram 341.1nay be 9 is located below the support.

adjusted vertically with respect to the cross head 32. The upper ends of the posts 36 Vof the ram 34 are slidably mounted in the upper part of the frame 1, as indicated in Figure 1. 1 n

n order to impart rotation to the shaftV 27, the same is supplied with a crank arm `38 to which the lower end of aV link 39 is sition shown in the drawings by stops 11 and the latch 12. Y The flask 9 is mounted on the support 4. rlhe sand 43 is placed in the flask 9. Through the instrumentality of the lever 40, the link 39, the crank arm 38, the shaft 27, the ,ranks 30, the pitmen 31, the cross head 32 and the posts 36, the ram 34 is brought downwardly upon the sand 43 in the flask 9, and the sand 43 receives the impress o" the patterns 8 and 35. By means of the lever 40 and coacting parts, the ram 34 is lifted from the flask 9. The latch 12 is retracted from engagement with the support 4, and the support 4 is reversed on an axis represented by the shaft 5, so that the flask The table 14 is swung horizontally, the standard 17 rotating in the bearings 18. In ,this way,

the table 14 is brought beneath Vthe flask 9 which has been inverted, along with the table 14. By way of the handle 29, the sha-ft 26 is rotated, and the cams 25 elevate the plungers 22, the plungers cooperatingI with the wear plates 21 to elevate the table .14 up to the inverted flask 9, the standard 17 sliding vertically in the bearings 18. The clamping means 42 are released, leaving the 'liask 9 and the molded sand o n the table 14, whereupon the table may beV lowered, by a manipulation ofthe handle 29, the table then being swung outwardly into'the position shown in dotted lline in Figure 3 to carry thev flask and the mold clear out of the machine. The flask and the mold then may be lifted olf the table 14 and be carried to any position where they are to be used.

Any suitable means may be provided 'for holding the flask 9`v on the support 4, whilst the support is being reversed. Thus, recourse may be had to a U-shaped yoke extended beneath the support 4 and provided ,in its upright arms with slots 51 which receive the shaft 5, so that the yoke 50 can be moved vertically. The arms of the yoke 50 have extensions 52 terminating in hooks 53, turnbuokles 54, or like adjusting devices, be-y ing interposed in the extensions 52. The hooks 53 are adapted to receive, removably,

a holder 55, such as a rod, shown in dotted line in Figure 1,'the rod 55 extending across the flask 9. A cam lever 56 is mounted at 57 for swinging movement on the intermediate' portion of the yoke 50 and is adapted .to cooperate with one of the vconnections 6 which unites the shaft 5 with the support 4. It wi-ll be clear that, by operating the cam lever 56, the yoke 50 will be moved downwardly, thereby causing the rod to hold the flask 9 on the support 4. n

Having thus described the invention, what is claimed is 1. In 'a device of the class described, a`

frame, a table, a support, means for holding a flask on the support, means for mounting the support on the frame for reversal with respect to a horizontal axis, means for mount ing the table on the fra-me for horizontal swinging movement and for vertical sliding movement to permit the table to be swung beneath thesupport and to permit the table to Vbe raised with respect to the support, when the support is reversed; and a rainmovable on the frame and located above the support.

2. A device of the class described, constructed as set forth in claim 1, and further characterized by the provision of mechanism for operating the ram and mechanism for raising the support, each mechanism including a shaft, and one shaft being mounted to rock upon the other shaft.

3. 1n a device of the class described, a frame, a table, a support, means for holding a `flask on the support, means for mounting the support on the frame for reversal with respect to a horizontal axis, means for anism including a plunger slidable in the frame and cooperating with the table, a shaft', Vmeans for operating the sha-ft, means for mounting the shaft on t-he frame for rocking movement, and a cam carried by the shaft and coacting with the plunger.

4. A device of the class described, constructed as set forth in claim 1, and/further characterized by the fact that the first-specified means embodies a movable yoke, a flaskengaging holder assembled with the yoke, and means vfor operating the yoke to cause the holder to cooperate with a liask.

in testimony that I claim the foregoing as my own, l ture.
